No, there's no time for revision, getting through AS maths before the exams is always tight, your DD should be already revising at home, C1 and C2 past papers weekly.

That said, not having started the third module yet is cutting it fine. My group have finished C1 and S1 and are partway through C2 and I'm aware we need to keep up the pace to make it. I think it would be fair to ask the teacher what the plan is to ensure it's all done in time.

A level courses are bursting with content. Teachers have to choose between skimming/teaching it in the time available (still rushing but at least trying to cover everything once properly) and obviously revision time is the casualty.
